Confessions of a How to Book Junkie

How to Write: Advice and Reflections by the Pulitzer Prize-wining  Richard Rhodes
(ISBN 9780688140953)
This book is by the writer of diverse works such as The Making of the Atomic Bomb, and The Ungodly, a novel about the Donner party. He calls "non-fiction" works verity,  the better to describe a genre that includes essays, biography, reportage, and historical narrative, and the book is somewhat slanted in that direction. Not much about short story writing, except for the useful analogy of "Short Story is to Novel as Essay is to Autobiography."
There's an excellent chapter on editing, as he takes the reader through the process he uses to write an essay, complete with revisions and re-typings.
He also has a unique description of POV: he calls what I've come to understand as "tight third person"  indirect first person. When writing closely from the POV of one character, he explains, it's like writing first person with all the "I's" changed to he or she. That way interior monologue can fit into third person narration.
